“No matter what driving conditions are like or what local circumstances are, there is probably always an alternative solution available from Scania, right here and now,” claims Magnus Höglund, responsible for alternative fuels and powertrains at Scania Trucks. “This launch lets us demonstrate to all types of transport players that they can reduce their CO2 footprint very simply, without giving up anything or incurring significantly higher costs.”
The newest and most spectacular item in Scania’s offer is the hybrid truck now premiering and being test-driven by European trucking and environmental journalists. The hybrid solution, developed by Scania itself, allows an 18-tonne distribution truck to operate solely on electric power for up to two kilometres.
Electric operation is primarily intended for situations where other solutions don’t measure up, for example, city distribution at night in noise sensitive areas or driving through warehouses and car parks where one doesn’t want any exhaust fumes at all. Electric power is combined with Scania’s 9-litre Euro 6 engine with 320 hp, which can be operated on 100 percent biodiesel, such as FAME or HVO. With this latter fuel, CO2 can be reduced by as much as 92 percent.
“It’s a very special experience to drive a heavy truck when the only sound comes from the hissing of tires against asphalt and a mild breeze,” explains Höglund. “What we’re seeing here is the beginning of a revolution that will make a big difference. Soundless and partly exhaust-free trucks can do a better job in cities at night with goods distribution, cleaning, waste collection and other city maintenance tasks. Hybridisation can also lead to a higher utilisation of every single vehicle when the range of uses expands.”
Scania was the first manufacturer to sell and deliver Euro 6 engines, the highest emission classification in Europe, which makes a huge difference when it comes to reducing emissions. Scania was also the first
to market a complete engine range based on three different biodiesel platforms, which can provide up to 65 percent CO2reduction when using FAME fuel.
Moreover, in 2015 Scania gave the green light for using HVO in existing Euro 5 and Euro 6 engines. This renewable biodiesel fuel can yield up to 90 percent reduction in CO2emissions.
“This product launch provides our customers – as well as their customers, who are often the driving force when it comes to environmental aspects – with unsurpassable choices of alternative fuels for their business,” adds Höglund. “The biodiesel engines range from 250 to 580 hp and are suitable for everything from light service to really heavy operations. And our introduction of a 280 hp ED95 engine for Euro 6 is unique in our industry. From an environmental perspective, bioethanol is an unusually smart, inexpensive and easy-to-handle alternative fuel that is also readily available in large quantities.”
Green light for HVO-use in Scania Euro 6 range
Scania has given the green light to hydrotreated vegetable oil (HVO) being used to power its Euro 6 range, provided the fuel used meets technical specification TS15940. Vehicles using HVO – which chemically mimics fossil-fuel-based diesel – can under optimal condition achieve up to a 90-percent reduction in CO2 emissions. HVO does not affect a vehicle’s characteristics or its maintenance requirements.
Örjan Åslund is Head of Product Affairs at Scania. “We have decided to give our blessing to the use of HVO biodiesel in our diesel vehicles,” he says. “Scania is the leading manufacturer when it comes to
offering power trains for alternatives fuels, and we have considerable experience with the practical side of driving using HVO. It’s an alternative fuel that has relatively few disadvantages when compared to diesel, while also offering a large reduction in CO2emissions.”
Earlier this year, Scania approved HVO for use in all types of Euro 5 vehicles and all types of operations. In cooperation with customers, the company also initiated a field test in Sweden involving some 100 trucks with Euro 6 engines.
“Thanks to the certification and our own decision, all Scania hauliers with Euro 6 engines can use HVO, including in buses,” says Åslund. “I know that interest is very high. The challenge for most operators will be in getting access to HVO, as both production and distribution facilities are still limited.”
HVO is a biofuel that has been much discussed in recent years, and a number of leading manufacturers have incorporated HVO into their ranges. The fuel is based on either vegetable oil or animal fats. Hydrogen gas is used to create hydrocarbon chains that mimic fossil-fuel-based diesel. This means that the fuel can also be distributed and used in the same way as regular diesel, including with regard to its thermal- and storage properties.
The certification of HVO complements Scania’s already marketing-leading range of Euro 6 engines and power trains for alternative fuels. Scania has for some time offered five Euro 6 engines for use with FAME biodiesel, as well as two gas engines. Scania has additionally indicated that both bioethanol- and hybrid solutions will also be introduced shortly.
“Scania is continuing to take the lead in products and services for sustainable transport,” Åslund says. “From Scania’s perspective, it’s clear that a variety of solutions are needed in the form of different alternative and renewable fuels. And to meet the global climate challenge, it’s necessary to explore several different avenues, ranging from more efficient vehicles to smarter transport and renewable fuels.”
